Rotten Teeth: What Can Actually Be Done, Whatever the State of Your Smile

If you have searched for this, the odds are you already feel bad about it. Perhaps it has been years since you saw a dentist, perhaps a tooth has been crumbling quietly for a while, and perhaps the thing that has kept you away is not money or time but embarrassment. So the most important sentence in this article comes first: dentists do not judge rotten teeth, they treat them, and there is no mouth so far gone that nothing can be done. Whatever you are imagining the reaction will be, the reality is a clinician who has seen far worse and whose only interest is a plan.

The short answer

Rotten teeth are teeth where decay has broken down the enamel and eaten into the softer dentine underneath, sometimes down to the nerve. Very early decay can be halted and even reversed. Established decay cannot regrow, but every stage of it is treatable: fillings for smaller cavities, crowns or root canal treatment for deeper damage, and extraction with replacement when a tooth is truly beyond saving. The starting point is always the same, an examination and X-rays so you know exactly what you are dealing with, which at Bollington Dental Practice is £89 for new patients.

What “rotten” actually means

Tooth decay is bacterial. The bacteria in plaque feed on sugar and produce acid, the acid dissolves minerals out of the enamel, and given enough time it breaks through into the dentine beneath, which is softer and decays faster. Left further still, decay reaches the pulp at the centre of the tooth, where the nerve lives, which is when toothache, abscesses and infection arrive. Our guide to tooth decay and cavities covers the process in detail.

What that means practically is that “rotten” is a spectrum, from a brown-stained groove to a broken-down stump at gum level. The treatment differs at each stage, but there is a treatment at each stage.

What can be done, stage by stage

Very early decay: halt and remineralise. A chalky white or light brown patch where enamel has started demineralising can often be stopped in its tracks with fluoride, improved cleaning and diet changes, and no drilling at all. This is the only reversible stage, which is exactly why check-ups exist.

Cavities: fillings. Once decay has broken the surface, the decayed material is removed and the tooth is filled. Our fillings start from £95 for amalgam and £125 for tooth-coloured composite, and our guide to white filling costs explains the difference.

Deep decay reaching the nerve: root canal treatment. If bacteria reach the pulp, the infected tissue is removed, the canals are cleaned and sealed, and the tooth is saved rather than lost. Root fillings here start from £305, and a back tooth that has had root canal treatment usually needs a crown afterwards for strength.

Badly broken-down teeth: crowns. Where too much tooth has gone for a filling to hold, a crown rebuilds it. Crowns start from £600, and our crown cost guide covers the options.

Teeth beyond saving: extraction, then replacement. Some teeth genuinely cannot be rescued, and removing them ends the pain and infection they cause. Extractions start from £126. The gap can then be replaced with a bridge, a denture from £625, or a dental implant, where a consultation is £180 and a single implant with its restoration starts from £3,000. Nobody has to live with visible gaps.

For a mouth with several problems at once, the plan is staged: pain and infection first, then stabilising the decay, then the rebuilding, spread over visits at a pace you can manage. You will have a written plan with every cost on it before anything starts.

If embarrassment is what has kept you away

You are not unusual, and you will not surprise us. A large share of the patients we see after years away open with an apology, and none is needed. Some of our longest-standing patients first came through the door after decades of avoidance, and the pattern afterwards is almost always the same: the dread of the first appointment turns out to be the worst part of the whole process.

If fear rather than embarrassment is the barrier, that is normal too, and it changes how we work rather than whether we can help. Our guide for nervous patients explains exactly what we do differently, from the first phone call onwards. The first appointment is a look and a conversation. Nothing happens at it that you have not agreed to.

What it costs, and what the NHS covers

On the NHS, treatment for decayed teeth falls into the standard charge bands, though NHS availability for new adult patients is limited across the country, and we are currently unable to take on new NHS adults ourselves. Privately with us, the numbers above apply: examination £89 including X-rays, fillings from £95, root fillings from £305, crowns from £600, extractions from £126, with everything published openly on our fees page. Once your mouth is stable, our dental plan from £15.95 a month covers the routine exams and hygiene visits that stop you ever being back here.

A candid note on priorities: a mouth with active decay in several teeth is rarely fixed in one go, and does not need to be. Stopping the spread costs far less than rebuilding, which is why coming in sooner, at any stage, always shrinks the eventual bill.

Frequently asked questions

Can rotten teeth be fixed?

Almost always, yes. Small cavities are filled, deeper decay is treated with root canal treatment and crowns, and teeth that are genuinely beyond saving are removed and replaced with a bridge, denture or implant. The right option depends on how far the decay has gone, which is what an examination and X-rays establish.

Can rotten teeth repair themselves?

Only at the very earliest stage. Enamel that has begun to demineralise can re-harden with fluoride and better cleaning before a cavity forms. Once decay has physically broken through the surface, no toothpaste, rinse or remedy can rebuild it, and waiting only lets it deepen.

Will the dentist judge me for the state of my teeth?

No. Decayed teeth are what dentists treat all day, and patients returning after years away are a normal part of every week here. The appointment is about a plan, not a verdict, and you decide the pace of everything that follows.

Do rotten teeth have to be pulled out?

Usually not. Extraction is the last resort, used when a tooth is too broken down or infected to rebuild. Most decayed teeth are saved with fillings, root canal treatment or crowns, and a dentist will always tell you honestly which side of that line each tooth is on.

Ready when you are
